Throughout my career I have studied split-brain and other types of neurologic patients, in an effort to understand both the functional lateralization in the human brain and how the cerebral hemispheres communicate with one another. These studies have contributed to identifying the complex mosaic of mental processes that participate in human cognition with the left hemisphere specialized for language and speech and major problem-solving capacities and the right hemisphere specialized for tasks such as facial recognition and attentional monitoring. Even though the brain has a modular architecture, we discovered the left brain also has unique capacity to interpret the multiple actions of these modules which in turn allows for a personal narrative to be created.
